FANS of the fly-on-the-wall show Big Brother will be watching closely to see the exploits of Woking’s Nadia Almada.

Residents may be familiar with Nadia, originally from Portugal, who has worked at various businesses around the town.

She previously worked on the perfume counter at Allders in Woking and is employed part-time at Sainsbury’s in Brookwood.

Nadia, 27, also works as a bank clerk. A source says she works at Barclays Bank in town square, Woking, but the company was unable to comment.

Big Brother housemates have yet to discover Nadia’s big secret – she used to be a man and has undergone a sex change operation. Although it may not be long before they do and some housemates seem to have their suspicions.

On Tuesday, Nadia confessed to Big Brother in the diary room that she “feels guilty” about keeping her secret from fellow housemates after they quizzed her about not being able to have children.

A colleague from Sainsbury’s said: “It was really bizarre seeing her on Big Brother. Nadia never talked about her sex change but we all knew about it.”

Nadia is one of 12 contestants taking part in Big Brother 2004, the fifth series of the Channel 4 show.
